I'll be appearing at the Brighton Festival under their 26 Letters banner at an event entitled So You Want To Write For Children? at the Old Market on 9 May 2008 at 7.30pm. 

It's chaired by Nicholas Tucker, and I'll be there with the author Katy Moran and our editor at Walker, Denise Johnstone-Burt.  Tickets are £7.50 and can be bought through the link.  Should be fun.  I'll do my best.
